Our invention relates to printing presses and While originally designed for printing the names of colors on cans containing paint,`

it may be employed to advantage for print- 5 ing any desired information on cans or Vvarious other eylindricalobjects. Y In carrying out our invention We emplo a reciprocatory slide for carrying the cans pastsuitable printingmeanssuch as type, .l symbols, etc., which print `the desired information upon said cans. Said slide also carries an ink roller which keeps the type well coated with ink sothat the printing applied to the -cans or labels thereonwill be clear 15 and distinct. 1 y i Provision is also made for distributing the inkuniformly upon the ink rollerand vfor handling cans and other cylindrical articles of different sizes, and in 'order that theinven- ,20 tion may be fully 'understood vreference will now be had to the accompanying drawings,

in which:

Fig. 1 is a plan view of the'printingpress.' Fig. 2 is a brokenl longitudinal-section of 2.5 the press on line 2-2 ofFig. 1.

Fig. 3 `is a broken vertical crosslsectionfo'f the press on line'B-Sof Fig. `2. 1

Fig. 4 is an enlarged vertical section of the ink roller andv its supporting means.

Fig. 5 yis an enlarged`-fragmentaryL vertical section on line5-5 of Fig. 1, showing the printing means and an adjustable support therefor.

Fig. 6=is a broken cross section on lineG-' of Fig. 1, of a rotatable carrier for the cans or other cylindrical articles to be printed upon. `V n Fig. 7 isay section on line 7 of Fig. 3, showing ratchet mechanism employed in `carrying out-the invention. f y l Referring in detail to thedifferent parts,2 designates a suitable support :or table consistingo'f ajtop4, legs 6V and braces' 8. p The top 4 has-a longitudinal opening 10 andslideways 12 disposedn at opposite sides of said opening l16.` lll-designates va reciprocatory slide' or carriage mounted in the slideways l2 and arranged to be moved automatically in one di'- rection by means of a counterweight 16 and 5 a cable 18, andlmanually moved in the oppo- Land an eye 40 site direction byfmeans of a foot treadle 20, a connecting rod 22,l a levfer24 anda cable26'.

The' co'unterweight 16 operates in averti-` cal'guide 28 at one end of the table 2 while the cable' 18 runs over a sheave 30 an'd'is attached at its lower end to the counterweight 16 andat its upper end to an eye 32 threaded intothereciprocatory carriage 14. The trea-y dle 20 andthe lever24 are'operably united by the Aconnecting rodl 22 `and mounted' at one end uponfpivots 34 and 3.6, respectively- The cable 26 runs over a sheave38 andis attached at its opposite ends to the lever 24 y, whichlatter is threaded into the carriage 14. 42 designates ka rotatable carrier Vfor conveying the cans or other cylindrical articles B past the printing mechanism A hereinafter described in detail. Said carrier-42 consists of a horizontally disposed member provided with a `iXedly mounted gea'rw'heel 44 and `having a .circular recess `46 in itsA upper portionfor .the".reception-of the lower ends of the cylindrical articleswhich are firmly held, one vatr atime, in Vsaid recess l46 vby suitable means such as a spring pressed detent 48. Y

The rotatablecarrier 42 is VfiXedly Vmounted upon stub shafthaving-a reducedlower end 5.2 for entering any 'of the holes 5.4 inthe reciprocatorycarriage 14. Several rotatable carriers 42-of different diameters are pro,- vided for holding cans or other cylindrical articles of different sizes and as the gear wheel 44. of each carrier 42 must intermesh .with track-.56 it is necessary-to locate the holes 54- diierentdistances from said rack 56,as'shown by Fig. 1.- `The rack 56 is secured to Ethe upper innerside of one of the slideways i12 by suitable means such as vscrew 58.

Q60 -design-atesa vertically `disposed the carriage14nearvoneend of the? latter.

lhentherollerr 60A becomes worny out it can b'e readily replaced-by another` by taking -oi' the plate 64 which is held upon the yoke 68 by suitable means such as a screw 74.

76 designates an antifriction roller mounted between the plate 66 and the lower end of Vthe yoke 68. Said roller 76 is normally held provided with a fixedly mounted ratchet` wheel 88 which is rotated step by lstep by a ratchet lever 90 extending downwardly through a slot 92 in the table top 4 and connected to one end of a retractile spring 94 which'is attached at its opposite end to anV eye 96. The lever 90 is arranged in the path of an arm 98 depending from the carriage 14 so that as the latter approaches the en d of its movement to the left, Fig. 2, said arm 98 will contact with andrpuslithe lever 90 backwardly, causing it, through the ratchet ymech- Y anism, to rotate the disk 82 one step.

100 designates a vclamp for holding suitable printing means such as type Ain the path of the ink roller 60. Said clamp 100 is mounted upon an arm 102 adjustably mounted upon a standard 104, which in turn is adjustably mounted in a bracket 105 secured by suitable means such as bolts 108 to the'adjacent side of the table 2. The type A is reinovably held in the clamp 100 by means of a stationary jaw 109 and a removable jaw 110,'

which latter is held in position againstthe type by set screws 112. The arm 102 has a longitudinal slot 114 so that it may be adjusted backward or forward upon the standard 104 to bring the face of the type in line with the cylindrical articles to be printed, upon, and after-such adjustment said arm 102 is clamped against shoulders `116 upon the standard 104 by means of a plate 118`and a set screw 120, which latter is threaded upon a stud 122 projecting from the top of the standard 104. The bracket 105 has a plate 106 removably held in position by screws 124. By looseningsaid screws 124 the standard 104 may be adjusted vertically toposition the type A at the desired elevation for printing upon the cans or other cylindrical articles. o Inipractice the ink distributing disk 82 is coated with ink and a can or other cylindrical article B is placed'in upright position in the recess 46 of the rotatable carrier 42 where itis rmly held by the spring pressed detent 48. The treadle 20 is then depressed to effect the movement of the reciprocatorycarriage 14 to the right, Fig. 2. As the carriage14travels to the rightthe gear wheel 44 is rotated by the rack 56 and in turn rotates the carrier 42 with the cylindrical article B which is printed upon as it rotates in contact with the type A. When the carriage 14 reaches the end of its movement to the right the cylindrical article B is removed from the rotatable carrier 42, after which the treadle 20 is relieved of sutiicient pressure to permit the counterweiglit 16 to returnthe carriage 14 to its normal position at the left of the table 2, whereupon another cylindrical article to be printed upon is placed in position upon the carrier 42. As the `carriage 14 approaches the end of its movement to the left the arm 98 contacts with the ratchet lever 90 and pushes the same backwardly against the action of the spring 94, thereby causing said ratchet lever 90 to turn the disk 82 one step through the intermediary of the ratchet wheel 88 and cause said disk to distribute ink upon the roller 60 as it rotates in contact therewith.

From the foregoing description it is apparent that we have provided a printing press which is well adapted, for the Apurpose intended and while we have shown one form of theinvention we reserve all rights to suoli other forms and modifications lthereof as properly fall within the spirit and scope of the invention as claimed.
